To all (whom. it may co'rwem:

Be it known that I, VENDEL LszLLo B' KEFI, citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented-,certain new and useful Improvements in Armorsfor-Automobile-lVheels, `of which the following is a specification.

'My invention relates to armors for'automobile wheels, and the inventionconsists in an armor made up of two series of plates mounted one uponthe other and constructed and adapted to operate substantially as shownand described and particularly pointed out in the claim. In theaccompanying drawings, Figure 1 1s a side elevation of a section of awheel upon which my improved armor is shown in working position. Fig. 2is a longitudinal section of two of said plates and Fig. 3 is a crosssection thereof. Fig. 4 is a perspective view of one of the outer platesand Fig. 5 is a perspective view of one of the inner plates. f

The invention as thu's shown is an improvement upon the construction ofarmor shown and claimed in my patent issued June 16,1908, No. 891,830.In the said patent the plates are single and adapted to overlap at theirends, and are smooth internally and externally. They also are heaviestor deepest at their lniddle longitudinally and recessed transverselyover one end each so as to lap the end of the next succeeding platethereover and make a uniform outside or peripheral surface on the treadof the wheel. The present invention is made to overcome the objection tomy patented armor in this, that if one of 'those plates become impairedit had to be thrown away and a new one be substituted in its entirety.This made the armor unduly expensive because I found that such injurieswere quite frequent. Hence I conceived the idea of building an armorwith a dual construction and in which there is a permanent inner plate Aand an outer service plate B removably fixed thereon.l The latter isdistinctly a road contact plate which wears out sooner or: later and isintended to be replaced when this occurs. To this end the said plate isproj'vided with transverse corrugations 2 which are deepest at thecenter and take the immedr ate exposure to the road. Said plates", likeinner plates B, are of suitable metal, and

the outer plate lies upon the inner plate relatively as shown an'd issecured thereto by screws 3 or their equivalent. The outer plateoverlaps the inner plate at one end and the inner plate projects beyondthe outer plate at the other end in the same proportion, so that theouter plates will always .overlap the joints of the inner plates. or

`the two sets of plates will break the joints as shown. The inner platesare secured upon tire T by turnbuckle connections lv at leach sideengaging with chains C at the side of the rim as shown.

The plate B is preferably made out of a piece of sheet steel bent'substanially half round in cross sect-ion and adapted to lit4 snuglyover tire tube T. Eaid plate therefore is of uniform thicknessthroughout and comparatively light in weight, while plate A is ofsuitable cast metal, preferably, though it might be struck up.from sheetmetal vwith more or less pronounced ribs 2. The inner plates B also havena'rrow exposed edges 7 at each side extending outward beyond plates Aand turnbuckles 4 are attached thereto, two for each side near the endsof said plates. It follows that a cornplete unitary part made accordingto my in-l `vention consists of two plates A and B fastened together andarranged in respect to cach other relatively as shown, one end of cachplate projecting beyondV the corref spending end of the other plate andsaid plates adapted to match with the next pair of plates at both endsas hereinbefore described. j

To facilitate traction purposes, especially in climbing hills, thetransverse ribs 2 of plate A are preferably of ratchet like toothformation as shown in crosssection in Fig. 2.

Plate B is preferably struck up outwardly to form an offsetv or recess bat the point where the pivoted connection of turn-buckle 4 is made, theobject being to keep said connection out of Contact with the rubber tireand prevent wear and abrasion thereof.

IVith the use of this invention, tires as ordinarily constructed may bematerially lightened and madeft'hinner especially at the tread portionthereof, and there is also a saving of power in driving a machinebecause of the excellentl tract-ion results to be obtained' by its use.
